La Isla - surf spot statistics

La Isla in Peru is a consistent year-round surf spot, heavily dominated by ground swells, making it a reliable destination for surfers seeking powerful, clean waves. The swell is almost exclusively groundswell, with percentages ranging from 91% to 99% across all months, ensuring high-quality waves with minimal wind swell interference. The mean swell size varies from 1.4m in January and December to 2.0m from June to August, peaking in the middle of the year. Wind conditions are the primary limiting factor at La Isla, with bad onshore winds prevailing over 93% of the time in every month, often reaching 99-100% from April to November. The best wind conditions, though still rare, occur in January, February, and March, with 4-7% favorable offshore winds—making these months the most promising for surfers. Given these patterns, the optimal window for surfing at La Isla is from February to March. During this period, the swell remains strong (1.5-1.6m) while offering slightly higher chances of clean offshore winds compared to the rest of the year. The larger swell from June to August is appealing for experienced surfers, but the near-constant onshore winds make conditions challenging. If you prioritize wave quality over wind conditions, the mid-year months provide the biggest waves, but expect choppier surf. For the best balance of size and wind, early year surfing is ideal.

In February, La Isla in Peru offers consistent surf conditions with an average swell height of 1.5m and a solid period of 13.8s, indicating well-formed, powerful waves. The majority of swells come from the SSW and SW directions, with roughly 50% of waves in the 1-1.5m range and another 37% between 1.5-2.5m, providing ideal conditions for intermediate to advanced surfers. Wind conditions are less favorable, with only 7% of the time offering ideal offshore or light cross-shore winds—mostly from the NNE to ENE. However, dominant onshore winds from the S and SSE (over 45% of the time) often create choppy or blown-out conditions, particularly at mid-to-high speeds (10-30kph). When wind aligns, the spot delivers clean, powerful waves, but surfers should monitor forecasts closely for those rare optimal windows. The consistency in swell direction and size makes it a reliable winter spot, though wind remains the limiting factor.
